The WTFoxx Octave Fuzz PCB is a clone of the famous Foxx Tone Machine—an awesome fuzz that I can only describe as soft-and-fuzzy or as gritty-and-nasty as you want it to be. Match the diode pairs to get a superb octave-up with the flick of a switch, over a basis of fuzzy carpet of Big Muff proportions. The PCB is also wide enough to fit sideways in a 1590B, for those daring enough to attempt to install it like the original FTM!
Let me get a little personal here: this is the pedal circuit that started it all for me. Several years ago, I began my pedal acquisition journey and started modelling my first real, tricked out pedal board after Justin Chancellor’s. I was able to find many of the necessaries and usual suspects locally—your Boss Chorus, Delay, and Flanger, your ProCo Rat, and MXR Bass Envelope Filter were all more or less readily available. But some of the seemingly crucial fuzzes such as the Colorsound Tonebender and the Foxx Fuzz Wah Volume were nowhere to be found locally.
And then I had the wild idea of building my own pedals. Why not?
So with that thought, I began researching. The Foxx Tone Machine is a high gain, silicon transistor fuzz that came out in the early 1970’s. From a bird’s eye view, four transistors and two pairs of clipping diodes bears a resemblance to that other four-transistor high-gain silicon overdrive, but in terms of its circuit topography it is a very different beast. Whereas the BMP is composed of four nearly identical gain stages, the Tone Machine looks almost like a Tonebender with an additional gain stage after the tone control. Throw in the fact that the Tone Machine also achieves an obvious octave-up effect thanks to the Germanium diode pair, and the two are completely different animals.
After many trials and many errors, the day I finally got a working circuit was a day I will not soon forget. The Foxx is fuzzy, warm, and rough around exactly the right edges. It sat really nicely in the mix with several of my bands I was playing bass for at the time, either with the octave-up mode engaged or without. And guitarists in the know swear by it, as it yields a wide range of possible sounds from smooth solos to harsh and jangly punk riffs.
Again, this was the circuit that inspired me all those years ago to begin building pedals in the first place. Today, I am more than happy to share that inspiration in the form of this intuitively laid out WTFoxx Octave Fuzz PCB. Happy Building!

Conditions of Return:
Buyers are responsible for return shipping costs. If the item is not returned in its original condition, the buyer is responsible for any loss in value.
Depending on availability, the time I need to prepare an order for shipping varies. For custom builds, please allow 3-4 weeks lead time. For finished builds, please allow 1-2 weeks for processing.
Estimated Shipping Times:
Eco Post: 7–5 business days estimated distribution time for most destinations (see below), 10–12 business days estimated distribution time to Australia and Hong Kong.
Registered Mail: 4–8 weeks
I will do my best to meet these shipping estimates, but cannot guarantee them. Actual delivery time will depend on the shipping method you choose.
Postal systems around the world appear to still be adapting to the global impact of COVID-19. This means that shipping times may be longer than we had previously been used to. I ask that you please be patient while we track the status of your package together.
I ship out all pedal orders via Eco Post. This method is typically quicker than Registered Mail (advertised estimation is 7–5 business days, but due to the current situation has been known to take a bit longer, depending on the country), and it also features computerized tracking and proof of delivery.
This method is available in the following countries: Austria, Australia, Italy, Ireland, the United States, Belgium, Brazil, the United Kingdom, Germany, Denmark, South Korea, the Netherlands, Hong Kong, Greece, Japan, Norway, Spain, Poland, Portugal, Finland, France, Canada , Sweden, Switzerland, Thailand, Russia.
For PCB orders, you can choose between Eco Post and Registered Mail.
Customers living in Israel can arrange for Local pickup, just contact me for arrangements.
Customs and Import Taxes:
Buyers are responsible for any customs and import taxes that may apply. I am not responsible for delays due to customs.
Each Carcharias Effects pedal is hand-made by one person in his home workshop who loves making music, and making things that make music. Every purchase you make enables me to continue making more pedals, so your support is very much appreciated. That said, I take responsibility for the build quality of every pedal I make comes, and offer a 24-month warranty on each one, not covering normal wear-and-tear or abuse.
All the PCBs that I sell on this site were designed personally by me, but the fabrication is outsourced to third-party PCB fabrication services. Once they are designed, I order them in relatively small batches. I personally test every batch that I receive; however, as I am a strong believer in minimizing waste, there are cases in which I may sell perfectly functioning PCBs that might have some design flaw. I take responsibility for these design flaws (if any) and will specify their fixes or workarounds in the product's specific build document.
If you should encounter any issues with your product, please feel free to reach out to me via the contact form on this website. As I am based in Israel, I understand the inconvenience added by international shipping, and so I will be happy to assist in troubleshooting with you any problems before resorting to international shipping in case a repair needs to be made.
